iPhone:如何从左到右制作presentModalViewController动画
我正在展示带有动画的模型视图。默认情况下,它是从下到上的。如何让动画从左向右播放?我知道我可以使用导航控制器。但实际上呈现视图不需要导航栏,模态呈现视图也不需要导航栏。我仍然想要从左到右的过渡。
I am presenting a model view with animation. As a default it comes from bottom to top. How can I make the animation to go from left to right? I know I could use a navigation controller. But actually the presenting view does not need a navigation bar and also the modally presented view does not need a navigation bar. Still I want a transition from left to right.

您可以使用以下代码在呈现视图控制器时从右到左制作动画
You can animate from right to left while presenting a view controller by using the following code
只有四个
UIModalTransitionStyle
:就像你说的,导航控制器会这样推动。如果您不想使用它,则必须自己为视图设置动画。
There are only four
UIModalTransitionStyle
s:Like you said, a nav controller will push that way. If you don't want to use that, you'll have to animate the view yourself.
我在实现 Matthew 的解决方案时遇到了问题,因为在动画期间呈现模态视图的视图将不可见(相反,呈现视图将替换为窗口背景,然后模态视图将在其上进行动画处理),这导致了不和谐的体验。相反,我将模态视图作为子视图添加到当前 UIViewController 的视图中,并对其进行动画处理。我请求了不同的动画,因此我尝试更改一些值来表示您正在描述的动画,但我尚未实际测试下面的代码。
希望这有帮助。
I ran into a problem implementing Matthew's solution because the view presenting my modal view would not be visible during the animation (instead the presenting view would be replaced with the Window background and the modal view would then animate over that) which led to a jarring experience. Instead I've added the modal view as a subview to the presenting UIViewController's view and animated it across. I had a different animation requested so I've tried to change some of the values to represent the animation you're describing but I have not actually tested the code below.
Hope this helps.
UINavigationController
有一个navigationBarHidden
属性 - 如果将其设置为 YES,您可以获得从左到右的过渡样式以及导航控制器的其他细节,而无需可见导航栏。UINavigationController
has anavigationBarHidden
property—if you set that to YES, you can get the left-to-right transition style and the other niceties of a navigation controller without having a visible navigation bar.只是想展示另一个选项 - 这个选项允许您使用 UIView 动画从上到下呈现视图。
请注意,您必须在隐藏状态下添加新视图 - 确保动画在视图完全加载时开始。
Just wanted to show another option - this one lets you present the view from top to bottom, using a UIView animation.
please note you have to add the new view in hidden state - ensuring the animation starts with the view fully loaded.
你可以尝试这样的事情:
You can try something like this:
